Hair loss
Hair appears much more complex that they look and they play a vital role in our appearance. They are composed of strong structural protein called keratin. Below the surface of the skin is the hair root, which is enclosed within a hair follicle. At the base of the follicle is the dermal papilla. The dermal papilla is fed by the bloodstream which carries nourishment to produce new hair.

The dermal papilla plays a crucial role ,and is of great importance for the hair formation and growth cycle.

Each human head carries roughly 100,000 hair follicles.
Each follicle can grow many hairs over a lifetime: on average, each follicle grows a new hair around twenty times. Hair grows about 3-4 mm/day. This hair growth and loss is completely random. At any given time, a random number of hairs will be in various stages of growth and shedding. Over the years, the number of follicles capable of growing hair decreases naturally. The loss of these follicles is especially noticeable on the top of the head.

Although causes of hair loss are still not yet fully understood, it can be the results of several factors. The causes of hair loss can be genetic, due to hormonal changes or imbalances (childbirth, menopause), linked to nutrition (deficiency in certain vitamins and minerals), stress, diseases, medications, hair treatment (over styling and excessive brushing, dye, bleaching) and of course aging.

Hair loss can be permanent or temporary.

Hair loss sufferers will most of the time have the hair growth cycle disrupted by;

  1. an increase of (DHT) hormone, loss of connective tissue surrounding the hair follicle
  2. an increase in the inflammatory process in the scalp
  3. an increase in higher oxidative stress
  4. An increase in free radical damage

Of course with aging, the decrease number of hair follicles and size of follicle in the scalp will also lead to thinner hair shaft and an increase in hair loss.
